public class HiddenFileFilter extends AbstractFileFilter implements Serializable
Files that are hidden.
Example, showing how to print out a list of the current directory's hidden files:
File dir = new File(".");
String[] files = dir.list( HiddenFileFilter.HIDDEN );
for ( int i = 0; i < files.length; i++ ) {
System.out.println(files[i]);
}
Example, showing how to print out a list of the current directory's visible (i.e. not hidden) files:
File dir = new File(".");
String[] files = dir.list( HiddenFileFilter.VISIBLE );
for ( int i = 0; i < files.length; i++ ) {
System.out.println(files[i]);
}
